Vibration measuring principle
The vibrating probe is stimulated by a piezo and oscillates at its mechanical resonance frequency. If the probe comes into contact with material, the oscillation is dampened and this is electronically registered, and sent out as a signal. Once the probe is no longer comes in contact with material, the probe can oscillate again and a new output signal is generated.
The installation is generally on the side of the container at the height of the required measurement. When installed from the top of the container, it is possible to use an extension tube of up to 4m or an extension cable of up to 20m.
